Description: This function allows the user to generate sets with unique node and element ID numbers. The nodes may be included in multiple sets.
Usage:
1. DSI prompts:
> ENTER NEW NODE SET NUMBER (X) OR E TO EXIT
• Any integer greater than zero (0) is valid.
• If the user enters a node set ID number already assigned, DSI returns the prompt:
> NODE SET xxxx ALREADY EXISTS
2. DSI prompts:
> SELECT NODES
• The user may press the left most mouse button or "N" to select the node nearest to the cursor.
• If the user selects the same node twice while creating a node set, DSI returns the prompt:
> NODE xxxx ALREADY PICKED
• If the user enters DONE, DSI saves the set and prompts:
> X NODES INCLUDED IN NODE SET X
• If the user selects ABORT, DSI deletes the node set and returns the user to the NODE SET submenu.
